GRAIN-BINDER.

SPECIFICATION forming part Of Letters Patent NO. 423,524, dated March 18, 1890. Application filed June 24, 1884- Serial No. 135,860. (llo model.)

- elevator or other carrier delivering grain into the binding-receptacle or Within reach of the. gathering or the binding mechanism, of a pair of stripper-rolls one or both being fluted or armed with fingers or teeth for the purpose of positively delivering or forcing the grain into the binding mechanism, and driven by a system of gearing located on the machine in front of the grain and actuated by a driving-roll of the elevator, or a shaft in practically the same relative position, and itself driven at the rear of the elevator; in

the employment, in connection with the delivery mechanism, of a vibrating separator lever or arm intermediate between the delivery and the binding mechanism, acting in such manner-that. the separator-arm freely. allows the accumulated gavel to pass beyond it to the binding position and then is forcibly returned to its former position to separate the grain near the delivery'mechanism from the bundle gathered in binding position or receptacle and hold the former positively back as the bundle after being bound is ejected from the machine, thereby securing a complete separation of the bundle from the entangled stream of grain; in the employment, intermediate between the delivery and the binding mechanism, of a trip and separator lever or arm that, under pressure of the grain accumulated by the delivery mechanism, first yields outwardly a fixed distance to engage a clutch to start the binding mechanism, then yields freely to allow the accumulated grain to pass to the binding position, and is then positively returned to and is held in its first position to prevent the stream of grain from following the gavel as it is carried to the binding position and afterward ejected from the machine; in the arrangement of two rock-shafts, one below and one above the grain, one supported on and fixed to the harvestenframe and having secured thereto at its inner end a disengaging-pawl, and at its outer end, preferably at the butts of the grain, a fixed lever-arm, the other supported on and fixed to the frame of an adjustable binding mechanism, and having secured thereto at its inner end a trip-lever and at its outer end a lifting or holding-up leverarm sliding thereon, (on a feather or spline,) acted upon by a ledge on the main gear and held fixed as to the harvester-frame by a yoke or stops extending therefrom and connected to the other lever-arm, whereby the pawl may always remain with its clutch that controls the binding mechanism fixed on the harvester-frame, while the trip-lever is fixed as to the binding mechanism and accompanies the latter as it isadjusted forward and back on the harvester-frame to the varying length of the grain; and in the various other combinations and details of construction hereinafter pointed out and claimed.

In the drawings, Figure 1 is a rear elevation of so much of a harvester-platform and elevator, with automatic binding attachment, as is necessary to show my invention; Fig. 2, a front view of a portion thereof to show the gearing for driving the elevator-aprons and the stripper-rolls, and also showing a part of the tripping devices; Fig.; 3, a top plan view of the binding attachment; includingthe elevator-head; Fig. 4, a plani view of the harvester-gearing beneath the binding-table, and also so much of the binder-gearing as lies beneath said table; Fig. 5, a rear elevation of the binding attachment with the binder-arm down and moving toward the band-securing devices; Fig. 6, a like rear elevation, with the binder-arm farther advanced and at the point from which it commences its return movement to its position of rest; Fig. 7, an elevation from the stubble side of the binding attachment with the binding-table in section and the overhung bracket of the post-frame, and the parts which it carries omitted; and Figs. 8 and 9, details, respectively, of an adjustable cord-guide which I propose to employ and of the construction at the rear head of the elevator to carry the grain free of the sprocket-wheel.

In the harvester A is the rear sill of the elevator-frame spliced to the rear platform-sill A by a metallic strip Cb, which affords a bearing for the gudgeon of the inner platform: apron roller and a support for the idle sprocket-wheel common to these machines.

A is the main wheel turning loosely upon a short axle, which at its ends has small pinions running in segment rack-standards A and is carried up and down along the racks by a worm-wheel a and worm-shaft a extending up rearwardly toward the drivers seat, which is intended to be located behind the "elevator in this type of machines, and having atits extreme or outer end a crank whereby it may be turned to carry the axle along the 'standards, and thereby raise or depress the main wheel relatively to the main frame to adjust the latter. The main Wheel drives a prime pinion-shaft B,which, by means of a beveled gear b, having two concentric series of teeth, meshes with and drives, respectively, the beveled pinion b at the inner end of the shaft B, having crank 17 to actuate the cutter and thebeveled pinion b at the inner end of. the driving sprocket-wheel shaft E the cutter-crankshaft pinion engaging with the outer series of teeth on the beveled gear for speed, and the sprocket-wheel pinion en- 7 gaging with the inner series of teeth to gain power. r

C U are the inner and outer rear elevatorstruts, and C the lower elevator-apron; G a frame overhung from the front of the machine "by means of a supporting-bar c at its head for the purpose of carrying the upper elevator-apron, while allowing the heads of long grain to project through the throatway left at the rear of the machine.

As thus far described, the component features of the harvester do not differ essentially from those before alluded to., In the present case, however, I mount the pulleys at the upper end of the elevator-aprons in such manner that these aprons terminate slightly short of the head of the elevator itself, the upper apron preferably projecting somewhat beyond the end of theilower, and beyond them place stripper-rollsiic c the first forthe upper and the second for the lower apron, which rolls fill the space between the ends of the aprons and the head or delivery point, and, being positively driven in the proper direction, serve to take the grain as it is brought 7 up between the aprons and carry it onto the grain-chute. If they. were for the purpose of stripping simply, they might be made smooth; but with regard to their relations to the automatic binding apparatus about to be described, one or bothwill be made toothed or fluted, in order that they may not only act as "or teeth, as the lower, if so provided, may

wind the grainaround itself. They may be placed so that their axes will be in ascending planes carried through .the axes of the upper and lower drums of .the aprons which I they respectively strip, in which case the passage-way formed by the elevator would be straight clear to its head, as in harvesters heretofore used; but it is better, and permits a more effective action wit-h reference to the binding mechanism, to place them, respectively, slightly below said planes, thus causing the passage-way to assume a practically horizontal position at the head of the eleva tor, as shown; or they may even be'placed so low that the passage-way will curve downward to connect with the grain-chute at the discharge or delivery point. I

For the purpose of driving the elevating and stripping mechanism, and alsothe platform-apron, and also for the purpose of removing the driving-chain at the rear of the machine from its former position, where it interfered with the purpose of the open throatway at the rear of the space between the two elevator-aprons, I have adopted the following arrangement of gearing: From beneath the sprocket-wheel D at the rear end of the shaft B driven from the main wheel, as before described, or in any other suitable manner, I lead the chain directly to apoint beneath the sprocket-Wheel D on the gudgeon of the inner platform-apron roller. Passing it up over this wheel, I carry it beneath the idle sprocket-wheel D located in the usual place, thence up and over the sprocket-wheel D on the gudgeon of the upper drum or roller of the lowest elevator-apron, finally from this returning it over the outer periphery of the driving sprocket-Wheel to its starting-point. Thus it is laid in such position A that it will nowhere interfere with the open throatway while still driving the parts in the proper direction.

-On the front gudgeon of the driven drum of the lower elevator-apronis keyed a pinion d, which meshes with and drives a spur-wheeld, turning on a stub axle or pivot fixed to the elevator-frame or some suitable support, and having no'function except to transmit motion,

' which it does, in the first instance, by driving the pinion d of the lower stripper, and being set out from the frame or support sufficiently to admit between itself and the wall of said support the pinion d of the upper drum of the overlying elevator-apron. A long driving these instrumentalities is concerned,

they are in veffect a shaft coincident with the axis of the roller which they carry, and may et-Wheel at .the head of the "lower elevator apron have been permitted to project beyond the supporting-surface for the grain at this point, as their-tendency naturally seemed to with teeth or chain.

be to assist the grain onward toward the chute; but they prove also quite, if not more, liable to clog and tangle with it and to thrash out the full ears with which they are constantly coming in contact, and the chain is permitted to close upon and carry down these cars and the stalks. Therefore in this machine the casting D bolted to the rear elevator strut or board and supporting the wormshaft of the main-wheel-adjusting apparatus, is carried up to aiford a bearing for the axle of this sprocket-wheel, and above the axle widens and terminates in an outwardly-extending flange d, concentric with the axle and on or slightlybeyond the crest-line of the teeth, thus serving to support the grain and carry it past the wheel without contact either The flange is intended V zto practically bridge the gap between the gteeth of the wheel and the rear face of the elevator-strut or of the body of the casting,

which is necessarily of appreciable width. Itmay, however, be omitted if this space is though to less advantage.

The extension of the casting D -alone, without-. furth er change over the ordinary construction, would present a shoulder projecting above the rear board to obstruct the grain, so that the object sought would be neutralized; hence a guide-piece D is secured to this Qr'ear board, inclining up above the edge thereof until it abuts against the casting and otherwise closed, or even when it is not,

jformsfa flush joint with the flange, sothat the grain as it is carried up is gradually and easily liftedto the crestof this flange.

The binder frame uponwhich I have chosen to exhibit my improvements and to which. some of them are more especially applicable is composed, as in machines already well known in the art, of a tubular post E, either at the front or rear of the table, pref erably the front, a tubular arm E subtendingthe table from this post to the neighborhood of the slot for the play of the bindingarm, and a tubular bracket E overhanging the table to practicallythe same distance. These three members, by meansof diagonal connecting-Webs at the meeting points, are readily made as ,a single casting, which is {supported upon feet e, running upon-removable rods orguides e mounted in brackets e e? from the end 'sill, one of which brackets in each pairto wit, the bracket e is cupped or flanged to support the feet when the rods are withdrawn, whereby not only is the frame readily adjusted back and forth to compensate for varying lengths of grain, but the machine-easily dismantled Without necessitating a large force of assistants.

A standard 6 from the inner end of the tubular subtendin g arm affords means for the attachment of the stock-eflwhich carries the =the'table.

upon an' inclined pivot. f'," secured to the knotter or twister andband holder, with such other immediate accessories tothe'knotting or twisting devicesas may be desirable. The

head of this stock is'broad and fiat, aifording a seat or bracket for the support of the outer part of the binding-table E and on the ver tical post opposite is a horizontal offset a also affordinga seat orv bracket for the sup-r metallic saddle-pieces 6 two or more in line with each other, having squared grooves with vertical'sides, and which sit over and snugly embrace ways a squared or of plate metal, also presenting vertical sides, secured to the elevator-frame parallel with the guide-rods 1 upon which the binder-framemoves, so as to form the inner track for the back-and forth adjustment of the bindingidevices. A further purpose served by this arrangement is that the ways and saddle pieces serve to tie the binder-frame and whole binding attachment to the harvester, dispensing with the brace- -rods or tie-pieces heretofore commonly stretched from the overhung bracket to a beam or carriage thereon above the elevator-head, and that they permit the bindingtable to be lifted off'from above the mechanism which it covers whenever the two bolts fastening it to the binder-frameare reendwise. The table has the usual ledges E secured to it and extending along the slot for the play of the binder-arm, and also up toward the head of the elevator .to lift'the 'moved, instead of requiring it to beslid 01f waist of the gavel and allow the band material to be carried cleanlyybeneath, and is braced at the outer end of the slot by an inverted bridge Eipermitting the pointof the binderarm to sweep entirely through in ejecting the bound'sheaf.

Severaliof the features thus far enumerated look toward the rapid and facile dismantling,

of the binder. To completely work out this object, the lever F, by which the adjustments the binder by means of ahooked link F, pivoted to the shank of said lever and catching into an eye-plate f, bolted to the underside of the table at its rear end. This lever," or a similar lever for the purpose, has usually been located at a distance from the table,- mounted upon a horizontal pivot, and conveying its power by means of a rock-shaft or to compensate for length of grain are'made by the driver or attendant,is connected with series of connecting-links and elbow-levers to In the present instance it is placed outer elevator-strut at the rear of the machine andat nearly right angles'to the slopev of such strut, so that the lever vibrates in a plane nearly parallel to such strut, thus bringing the hand-hold up within the reach of the driver in his seat at the rear of said elevator and dispensing with all intermediate connections except the single link, which can be readily hooked into or unhooked from the eye-plate, so as to entirely detach the lever from'the table when the latter is to be taken off 'or the binder attachment removed.

' wheel is turning.

Coming now to the active mechanism of the binder, a pinion G, fixed to the sprocketwheel shaft before mentioned, drives a spurwheel G, loosely mounted on a counter-shaft G but capable of being locked thereto by a sliding clutch-half G pressed constantly to ward the wheel by a coiled spring g, so that unless forcibly held away it will engage with the wheel and cause the shaft to turn. Upon the'sliding half of the clutch is a peripheral flange g,which'upon the face toward the wheel at one point presents an incline g terminating finally in a stop. or'shoulder 9 the purpose of this being topermit the trip-dog hereinafter described to force the slidin g half away from the wheel, and, finally, by coming against the" stop when the clutch is fully disengaged, to lock the shaft positively against motion in the direction in which the This counter-shaft G is mounted in brackets on the harvester-frame, and has a long groove extending between two ofthese brackets, whereby the sliding pinion g, which communicates motion to the detachable parts of the binder, is splined to said shaft and permitted to slide longitudinally thereof between the bearings as the binder is adjusted. A gear and cam wheel H, similar to those heretoforeemployed by me for the purpose of operating the twisting or knotting' and holding and cutting mechanisms, except in a single feature hereinafter explained, engages with the slid- -ing pinion, being itself mountedat the end an'adjustable crank H, such as referred to by me in an application heretofore filedto .wit, on the 17th day of 'April, 1883, Serial No.

- 92,02land the binder arm H is link-sus- Beneath the binding-table is also hinged a cam-block H fl'supporting at its outer end an elastically-yielding compressor H, which is carried up through the slot in the bindingtable and held stationary there for a proper interval, and then permitted to descend by means of a couple of rollers h'h', mounted upon the'ends of crank-arms h it from the inner or rear end of the shaft turned by the gear and cam wheel. These parts, and othersnot by themselves novel in the present application,

are referred to for the purpose of explaining the operation of the improvements and on account of certain particular combinations here? inafter pointed out, into which they enter as eifective elements. or as representatives of well-known equivalents.

A bar Iis bolted to the overhanging bracket at its inner end and extends over the binding-table nearly or quite to the head of the elevator, being shown herein as passing slightly above the overhanging support of the j upper elev'ator-ap'rombut not attached theresuitable manner firmly secured to the frame.-

The rear bearing of the rock-shaft ofcourse moves with the adjustment of the bindingtable and the rock-shaft moves with it. It therefore slides inthe front bearing. front bearing is split or forked to receive and hold against lateral displacement the hub of an arm 71, which, by means of a spline-andgroove connection with the shaft, is caused to :partake "of its rocking motion and act as a crank arm or lever. The outer end of this crank-arm is connected by means of a link I with a second crank-arm 7/ from the end of This therock-shaft 1 mounted beneath the hind ing-table and passing rearwardly from its first bearing 71 on the outside elevator-strut to a point opposite the tripping-clutch'before alluded to, where it is received in a second bearing 71 formed in the bracket-I bolted for convenience to one of the'inclined bracebars of the outer struts of the elevator-frame. This shaft, having both bearings upon the ele- ,vato'r-frame, is of course'free from longitudinal movement. Near to'its rear bearingithas secured to it a dog t so arranged that its nose vibrates in a plane passing between the sliding and fixed halves of the tripping-clutch.

Thus when the dog is depressed by the movement of the rock-shaft, however caused, it

will .enter between the face of the spurwheel or the hub formed thereon, and the peripheral flange-on the sliding half of the clutch, and as the two, previously locked together, continue to turn it will strike the incline on said flange and, riding up it, will force the sliding half away, until finally the clutch is disengaged and the noseof the dog has come in contact with the stop on the flange, locking the counter-shaft against further ,movement.

The most convenient means to accomplish the depression of the tripping-dog is a spring i seated between a shoulder on said dog and anoffset from the bracket in which the rock-shaft is borne, and having sufficient strength to move both rock-shafts and their attachments and any additional strength that may be found necessary or desirable. It is evident thatwhen the dog is lifted from between the sliding and the fixed half of the clutch an immediate engagement will ensue and the binder be started by the harvestergearing; and for the purpose of causing such lifting of the dog and consequent-engagement of the clutch by the accumulation of thegavel, I mount upon the inner end of the first or upper rock-shaftthe one which slides with the binder-an arm K, properly curved and depending, so that its nose reaches alongside, or'nearly so, one of the two grainledges on the binding-table at any suitable point, either at the junction of said table ment will be simultaneously communicated to the lower rock-shaft and thereby the tripping-dog raised and the clutch caused to engage. In case the clutch-shaft revolves once to each revolution of the binding mechanism, the disengaging or trip dog needs noth- ,ing but the trip-lever and connecting devices to disengage and the spring to engage it; but whenthe clutch, as in the present gearing, revolves several times during one revolution of the binding mechanism, other instrumentalities will have to be employed to prevent the binding mechanismbeing stopped at each revolution of said clutch. To this end a lifting or holding lever K is employed, having in this instance where the binder is adjusted a hub feathered to the lower rock-shaft to slidelongitudinally thereof, but partake of its rocking movements, and forked to embrace the gear and cam wheel (the main gear of the binder) sov asto accompany the binder-frame in its adjustments. One arm 70 of the fork is prolonged .-to comein the path of a ledge 7c onthe face of the gear and cam wheel, so that immediately after the clutch has been tripped and the binder started the ledge comes beneath the now raised arm and prevents it from falling until the revolution of the gear and'cam wheel itself is nearly completed, when the ledge passes out from beneath the arm and permits it, and consequently the trip-dog, to fall in time to disengage the clutch to terminate with the fullrevolution.

If the arm K, hereinafter called the trip arm or lever, should berigidly secured to its rock-shaft, it is evident thatthe binding mechanism would be started by the accumulation of the same quantity of grain 'under like conditions every time, and that there would be no control over the size of the gav-' els and the sheaves which they form. The conditions varying, as from wet to dry, the

size might vary and would be in no way subj ect to the judgment of the attendant. It is preferable, therefore, to mount the trip-lever looselyupon its rock-shaft and to key to this shaft a segment or other plate K having a series of perforations one above the other, either arranged concentric with the axis of the shaft, as shown, or in a straight or zigzag manner, as may seem advisable. A thumbscrew or bolt, or other'stop k is adapted to x be inserted intoany one of these holes, and

by inserting it nearer to or farther from the trip-lever in its normal depressed condition the latter will rise to a less or greater distance before it becomes rigidly engaged with the shaft so as to move it and effect the tripping action, thus hastening or postponing this action-and diminishing or increasing the size of the bundles.

fore stated, to the overhanging bracket, and

is at one end connected by a link k with the trip lever somewhat inside the pivot of the latter. The other end is bent downward over the binder-arm shaft and provided with a straight inclined shoe k and a segmental shoe 70 A cam K is mounted upon or cast solid with the hub of the binder-arm crank, or else keyed to the shaft just inside that hub beneath the bent endv of the pivoted arm; This cam has a segmental trackway k corresponding in length to the distance which the shaft travelsin carrying the binder-arm fromthe. point in which the. grain should be cut ofi around and up to near its position of rest at the moment the binder is thrown out of gear.

At the innerend of the segmental track is a roller k sunk in a recess in the cam, so as to expose onlyea portion of'its periphery, and as the cam revolves this roller strikes the inclined track on the end of the pivoted arm, lifting the end of the arm, and in itspassage over the withthe curvedshoe of the arm and locks the trip-lever in position until atleast the bound bundle has been discharged and in practice a-little later. When the binder-arm has reached its position of rest, (indicated in Fig. 1,) the segment has passed out of engagement with the curved track, and the triplever is free to yield again to start the binder.

To prevent the grain from passing beyond the reach of the trip-lever and acting as a separator, while the binder-arm continues its motion and before the trip-lever is fully down, a spring L is attached to that one of the grain-ledges alongside which the end of the trip-lever comes or to the grain-chute, so as to lie close to the path of the trip-lever and at a sufficient height to allow it to be bent concentrically with the axis of the lever and to lie throughout its whole length within the trajectory of the point of the latter. lhis spring holds back the grain that follows the binder-arm as the bundle is being carried into position, so that all behind the arm is embraced and swept back by the trip-lever in its descent. A second spring L is at-.

tached to the grain-chute near the rear of the machineand somewhat above the spring just mentioned for a slightly-different purpose-that is, it has been found in experience that when the bundle is ejected some of the grain, entangled as to the tops, is very apt to follow the bundle. Therefore this second or auxiliary spring is put in to catch and hold back this grain, and also in connection with the trip-lever to hold the accumulating gavel from dropping down and sliding endwise from the machine, for this purpose being so placed that it comes in the path of the heads of grain. It is shown as secured to the harvester-frame; but it may be attached to the rear of the table at its upper portion, pro vided that this part of the table extends sufficiently high.

Over the front of the table inside the windboard L is placed the shield or hood L ex tending from the head of the elevator nearly to the overhanging bracket of the binderframe and curved downward at its extreme outer end to near the gearing at the joint between the bracket and vertical post, that loose grain may not become entangledwith the delay-gears and clog or render uncertain the action of the machine. It serves also as a hood or cover to keep the grain from rising too high in the receptacle or shooting over the binding mechanism.

It has been my practice formerly to mount the cord-box M on a sliding carriage sup ported upon the overhanging bar which receives the weight of the upper elevator-apron frame, and to make this carriage also the inner point of attachment for the brace-rods which stayed the overhung bracket of the binder-frame. Now that these brace-rods are dispensed with by the use of the binding-table as a brace to the frame, as heretofore explained, the sliding carriage ,is omitted and the cord-box bolted to the overhanging bar through the interposition of a bracket m, one arm of which is secured to the box and the other to the bar; but as the binder is adjusted the direction of the cord led from the box might vary without some compensating device additional to the guides heretofore used,

and the binder-arm, which does notreceive the cord through an eye in its p oint, but

.catches over it at each binding operation,

might under some adjustments fail to catch or else catch between a guide and the box. For this reason I form guide-eyes m m in the end of the arm which supports the upper tripping rock-shaft, 'carryin g this end up close to or immediately above the elevator-head.

Two eyes in line with each other transversely to the overhanging bar are employed, as one eye must be near the trajectory of the point of the binder-arm, and if receiving the cord directly from the box might permit interference between itself and said box, andby using two eyes the rearmost can be set back in line with the cord-box and always hold the cord the'rebetween out of reach of the binder-arm.-

The position ofthe eyes is advisably made capable of adjustment, and this may be done by meansof the oblique brace-rod between the supporting-arm and the overhung bracket or otherwise by employing the construction shown in Fig. 8, wherein said eyes are formed in an independent plate M, connected to the supporting-arm by slot and screw M M the contracting faces of the two pieces being smooth or roughened, as desired.

It will be observed that the binder-arm in 1.
